Coverage under prefix YAX

EPO

This prefix is associated with an EPO plan. Exclusive Provider Organization coverage combines elements of HMO and PPO plans: members must stay in-network like an HMO, but can self-refer to specialists like a PPO. Out-of-network services are not covered except for emergencies.

Medicaid

Under this prefix, the member may have Medicaid coverage managed by this BCBS plan. Medicaid claims have specific rules around cost-sharing, balance billing, and timely filing that override the plan's standard commercial policies. Contact the plan's Medicaid provider services line for submission details.

PPO

PPO (Preferred Provider Organization) plans allow members to visit any healthcare provider without a referral. In-network providers cost less, but out-of-network care is still covered at a reduced rate. When billing for a PPO plan, submit claims directly to the payer listed above. No referral documentation is needed.
